title: Investigation of the durability of poly(ether urethane) in water and air.
abstract: In this study some relevant aspects of the durability of an aromatic poly(ether urethanes) was investigated. Hydrolytic and oxidative treatments at increased temperatures were applied. The induced changes in the materials under investigation were characterised by complementary polymer characterisation methods, such as ATR-FTIR, DSC and mechanical testing. The thermal and hydrolytic treatment did not significantly affect the chemical composition of the materials. Changes can be observed in the microstructure of the materials.
